Choose the correct solution set for each graph

Hello from MrBillDoesMath!

Leftmost graph:    x<= -2         or   ( minus infinity, -2]

Middle    graph:    (-5, infinity)

Right       graph:   (-2, 3)

Discussion:

I n the graphs the white circle means that value is NOT included in the set. For example, In the Right graph the values -2 and +3 (the "endpoints") are NOT included in the solution set.

In graphs ")" means the value is NOT included but "]"  (the square bracket)  means the value IS included.

Regards,  

MrB

 P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

1 is B and E

2 is A and C

3 is A and D

Step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

good luck on ur quiz test or homework. have a good day : )
